Post subject:  First Game for Review

Hello!

Okay, so I've decided to submit a game for review. My, uh, Go Sensei recommended this as a good way to progress, though I find it a little embarrassing and so I've been reluctant to do it.

The first thing you'll notice is that I'm not very good. I typically play bots (out of fear of human competition and more embarrassment), so I think that I probably have a poorly developed game in many areas, and that my "true ranking" would be far worse than my current KGS assessed strength.

I've read that it's best to post losses, so it was easy enough for me to go out and lose a game. In this one, I wound up feeling a significant time pressure, coming with a second of Sudden Death a number of times. But no excuses; I lost and lost badly.

Any assistance would be greatly appreciated, and thank you for your time!

Yours,

DA

Basic shape problems.

I like your choice of moves at 40. Locally, it is an ugly move. But considering the whole board tactical situation, I think it is best.

This is a very common feeling in beginners. You're not alone! But trust us, there are plenty of bad humans for you to play against.

Everyone gets stressed out about losing or playing badly I think. I know I do. But don't let that keep you from playing.

The previous guys are much more entitled to comment that is why this 7 kyu again couldn't resist.

:b2: 4-4 stones want to be left alone. Bother his at C14 or keep distance at K4 or K3 . Your G4 is not quite wrong but maybe a bit vague. If you really want to be vague play Tengen ( K10 ).
:b8: first wedge at D3. You should think first after his reply. His shape will be severely damaged.
:b10: It can't be wrong but it somehow gives me an uneasy feeling. It says: "please white, the initiative is yours". Maybe I prefer b F17. If he answers w C14 you play your b C11 ( or even better C12 ) naturally. But don't trust me on this.
:b28: do you really want to push him to the right?
:b34: You didn't need to descend to the second line to keep him separated. b E11 works as well.
:b36: I guess it was luck by which you saved your two stones. ( for example w should have played w61 at F9 and w 63 at F11 ) Better to cut your losses right here and go after his three stones with b G11. Your two stones will keep some value. White is not safe yet at all.
:b78: Not necessary yet. At least tease him first at b E11.
:b92: This is called an empty triangle. Change the baby's diapers anytime you play it. Good luck!

Cyclops is right. But there is a bigger principle behind what he is saying. In this instance, the 4-4 stones do want to be left alone. In a more general sense, any strong position wants to be left alone. ( and on a board this sparsely populated, a lone 4-4 stone is strong. ) G4 is too close.

D3 ( :b1:) would be a push, not a wedge:

Not recommended. You should definitely think BEFORE whether to push with :b1: --
ONLY IF you get a good result with :b1: should you play it.
Otherwise, :b1: only reduces B's own liberties (it also removes one ko threat for B).

:b10: is good direction.

:black:E11 is an empty triangle and does not work at all -- the :black:C11 stone dies even faster. :black:C10 is better.

Fortunately for you, your opponent did not see the tesuji that would have won the liberties race on the left side:
60: wG9
61: bF9
62: wF11
63: bE11
Then white continues the liberties race with
64: wA13
But now black needs an approach move, so white wins the race.

I would object less if ( hypothetically ) his initial stone was at 3-4. That one is even stronger but a second stone from it could finish the corner so it is less vague, less a half measure. So apart from strength maybe also balance is involved in the sense that 4-4 is more balanced ( or symmetrical or finished ? ) than 3-4. But I am sure these are only small considerations at my and OP's stage.

edit: I should have copyrighted "my" sequence, Joaz ;-)
